dc.description.abstract | Low temperature magnetic and thermal (Cm) properties of the ferromagnetic (FM) alloys Ce2.15(Pd1−xRhx)1.95In0.9 were investigated in order to explore the possibility for tuning towards a quantum critical point (QCP) by doping Pd with Rh. As expected, the magnetic transition decreases from T = 4.1K at x = 0 with increasing Rh concentration. However, the phase boundary splits into two transitions, the upper being antiferromagnetic (AF) whereas the lower FM. The AF phase boundary extrapolates to TN= 0 for xcr ≈ 0.65 whereas the first order FM transition vanishes at x ≈ 0.3. The quantum critical character of the TN → 0 point is inferred from the divergent T dependence of the tail of Cm/T observed in the x = 0.5 and 0.55 alloys, and the tendency to saturation of the maximum of Cm (TN)/T currently observed in exemplary Ce compounds when TN → 0. Beyond the critical concentration the unit cell volume deviates from the Vegard's law in coincidence with a strong increase of the Kondo temperature. | |
